Re: [CMake] [boost][b2] Differenciate 32bit and 64 bit binaries when using CMake.

I don't see a clear solution to achieve this, because it depends a lot on how boost have been compiled. Use a naming convention, e.g. set BOOST_ROOT to Boost-version-compiler, where compiler is either vs10 or vs10x64. Assuming that Boost is not your only dependency, a naming convention is way easier to implement than fixing all the Find*.cmake scripts. I can't guarantee where the boost libraries are installed, that's why I use FindBoost. Just make the CMake error message clear, e.g. Boost 1.50 expected to be found in dir. Most people know how to rename a directory.

Re: [CMake] Using different installs/versions of the OpenCV library
Have you tried specifying the version?
FIND_PACKAGE(OpenCV 2.2.0 EXACT REQUIRED)
FIND_PACKAGE(OpenCV 2.4.0 EXACT REQUIRED)
Not sure if the FindOpenCV script can handle the version argument.

Hello list,

find_package( OpenCV REQUIRED )

add_executable(framecountertest framecountertest.cpp)
target_link_libraries(framecountertest ${OpenCV_LIBS})
and this works just fine: the OpenCV library that got installed using my
package management system
on Ubuntu 12.10 is being used.
However, under the directory /tmp/opencv_install I have another manual
installation of a more recent
OpenCV library, and I would like to use that one instead of the default on my
system, or easily
switch between the two versions. How should I specify that in my
CMakeLists.txt file? I have tried
set(OpenCV_FOUND 1)
set(OpenCV_INCLUDE_DIR /home/bart/Git/Research/fat/inc/TraficonOpenCv/opencv)
set(OpenCV_LIBS

add_executable(framecountertest framecountertest.cpp)
target_link_libraries(framecountertest ${OpenCV_LIBS})
but even with these commands, still the default libs on my system are being
used...
What is the correct way to specify that I want to build with the install under
/tmp/opencv_install
? And how can I easily switch between versions without needing to remove one
or the other version?

Re: [CMake] Using different installs/versions of the OpenCV library
Does CMake find 2.4.3 if you remove 2.3.1? CMake probably doesn't even look in /tmp/. You could try moving it to /usr/share/OpenCV-2.4.3/. If the version arg doesn't work, I think your best bet is to use a naming convention for the library directories (or create symlinks), e.g. lib-version-arch, then use that directory in the find script.

Re: [CMake] Dependency for launching an application
Yay, that is almost what I want. Except that I'd like the launch target to behave exactly like the
parent target: When I select the project in Visual Studio, I'd like to press F7 to build it and F5
to run it (with the debugger attached). When using add_custom_target(), the exe is started at build
time. I've tried add_executable(.. IMPORTED), but it doesn't create a VS project.

Re: [CMake] External dependencies and Windows
DLL Hell becomes an issue when executing a program. The EXE needs to use the DLLs that correspond to the LIB files it was linked against. I think you're only concerned with building a library or an executable here. The way CMake is designed is that you simply call find_package(), and the FindX.cmake script is supposed to figure out the rest. When it comes to building a Windows installer for your EXE, only then will you have to be concerned with DLL hell (i.e. add all DLLs to the installer).

If package A installed python.dll version X.Y into C:\Windows\System32 and later package B installed version Z.F into the same place, package A stopped working. Further, packagers where essentially forced to include all dependencies in their packages because there's no dependency-resolution mechanism.

(Basically, in practice, there is no such thing as shared libraries in Windows - nothing for find_package to find.) What then are DLL's? They are the shared libraries of the Windows world. True, the semantics are a bit different, but they are dynamically linked. It's also not true that on Windows everything is a zip files that you're supposed to unpack right in your build environment. If you don't believe me, try to take a look at Qt or Python. So how am I supposed to write portable CMake scripts in face of this? Often the Windows packages are installed into a few well known locations, or even better, create a registry key containing installation information which you then can use to find the software in your CMake code.

Re: [CMake] retreiving the libraries the maven way?
CMake doesn't support this out of the box. For most library dependencies, it's not even possible to retrieve their version, because either the FindXYZ scripts aren't written properly, or because the library doesn't provide it in the first place. Every library and every Find script does things differently. E.g. some find scripts use find_package(Lib) and define Lib_FOUND, others LIB_FOUND. My favorite: find_package(Qt4) defines QT4_FOUND, but ALL OTHER variables are prefixed with QT_. I ended up setting up a library directory on our server which follows a simple naming convention, lib-version-compiler. On the local developer machines, a similar directory exists for the libraries. If a particular library directory doesn't exist locally, it is fetched from the server. Simple, stupid, but since there is no meta information available as part of c++ libraries, that's the best I could come up with. If you need more help I can post some scripts.

For java, I use nexus, which is a binary repository server, that provides an nice REST API that allows clients to download dependencies by providing the library name and a target version. I'm wondering if it would be feasible and difficult to port this logic into a cmake plugin, and allowing the find_library to seamlessly retreive the library from the system OR from a nexus server. currently all our dependencies are stored in the svn, which slows down our builds and is not very flexible. Let me be more specific by describing my usecase. 1- On a Windows PC, I need the zlib dll and the standard C dll to build my project 2- I issue a find_library command specifying both custom library paths and a nexus server URL 3 - for the standard C library, cmake findsout that it's already located into the system 4 - for zlib, cmake performs a request to the server which acknowledge the availability of the dll 5 - cmake downloads the library in a cache folder and tells the generator to link to the library it downloaded 6 - if the library cannot be found on the system and on the binary server, cmake fails 7 - the same thing happen on a mac system, but this time both the C lib and zlib are on the path, hence binary server is not even queried for a lib.

Re: [CMake] 'NMake Makefiles' generate does not support parallel builds (/MP)?
My bad, we're not using nmake but msbuild in Jenkins (command line only). Judging from the
compilation speed, I'm pretty sure it respects the /MP flag.

I'm creating a shared library target that needs to compile and include
source generated by an IDL. I want CMake to create a custom target
that will invoke MIDL.EXE (comes with Windows SDK) against the IDL

files will then be built by the shared library target. I saw a similar
post on this here:
http://www.cmake.org/pipermail/cmake/2011-July/045617.html
This seems complicated and I'm not sure it even works, since from my
tests, if source files don't exist by the time add_library,
add_executable, etc is called, generation will fail. I also don't want
CMake to invoke MIDL for me since that would require us to run CMake
again every time the IDL file changes (this shouldn't be the case, we
should just have to rebuild the target again using Visual Studio or
NMake).
Any ideas on a simple solution to this?
Thanks in advance.

[CMake] Defer compiler to different file in Visual Studio
Hello, I'm currently evaluating Lazy C++ [1], which generates both header and source files. I'm using add_custom_command() to invoke the generator on *.lzz file, and for each .lzz file it generates one .hpp file and one .cpp file. What I'm missing is the ability to compile the file I'm currently editing from within Visual Studio. With .cpp files it's possible to compile just one file, e.g. by right-clicking it in the Solution Explorer, then selecting Compile. Or even better, bind it to a hotkey. So what I'd like to do is for each lzz file, set the compile command to compile the corresponding cpp file. I can't imagine it being that hard, since one would merely have to change the file extension in the command line from cpp to lzz. Any ideas? I'm not sure though, this might be more of a Visual Studio-specific question than a CMake-specific one.

Lzz is not a compiler, but rather a code generator. I would set things
up so that you do something like this:
create_lzz_source_list(MY_CPP_HH_SOURCES foo.lzz bar.lzz car.zzz)
add_library(mylib ${MY_CPP_HH_SOURCES})
# create_lzz_sources would be a function that creates a bunch of custom
commands that run lzz on each lzz input file and create a .cpp and .hh
file. So, there should be a custom command for each .cpp and .hh file.
You should be able to click on one of those can select compile, and it
will run that file.
This is the exact type of thing that is done for the VTK code wrapper code.
Yea, that's pretty much what I've got so far. And yes, I realize that's
the way it's *supposed* to be set up. ;) I've posted my CMakeLists.txt
here if you want to have a look:
http://stackoverflow.com/a/9669388/872616
The only time I would really like to have anything to do with generated
files is if something goes wrong with the generation, but not during
normal development. I'd like to set up the tool chain such that I only
have to touch the .lzz files, and the .hpp/.cpp would be completely
hidden away in the build dir. Just as normally you wouldn't want to have
anything to do with .obj files, you know?

I don't think you can do that. However, you can make it a little nicer
with this change:
MAIN_DEPENDENCY ${CMAKE_CURRENT_SOURCE_DIR}/${filename}
From
Note that MAIN_DEPENDENCY is completely optional and is used as a
suggestion to visual studio about where to hang the custom command. In
makefile terms this creates a new target in the following form:
cmake --help-command add_custom_command
OUTPUT: MAIN_DEPENDENCY DEPENDS
COMMAND
However, when you right click on A.lzz and it will run lzz, and not the
full compiler cycle. You will have to right click on the generated .cpp
file to run the actual compiler. There is no way to collapse that into
one step.

[CMake] VS2010: /subsystem:console only in debug build
Hi, I'd like to suppress the console, but only in release builds. What's the official way to do that? add_executable(... win32 ...) doesn't work, because it switches off the console in debug builds. When I set LINKER_FLAGS_RELEASE to /subsystem:windows, I can suppress the console in the release builds. However, the Properties window in VS2010 still displays Console (/SUBSYSTEM:CONSOLE) in the linker settings, and has two entries in the command line: /SUBSYSTEM:CONSOLE and /subsystem:windows. Only the latter seems to count. When I set LINKER_FLAGS_RELEASE to /SUBSYSTEM:WINDOWS, CMake just drops it, and only retains /SUBSYSTEM:CONSOLE in the linker flags. It seems to me that CMake recognizes /SUBSYSTEM:WINDOWS, but chooses to ignore it for some reason. The fact that /subsystem:windows works the way it does seems like a bug. So what's the proper way to achieve what I want? I'm using CMake 2.8.7 on Win 7 with VS2010.
