[CMake] What do these CMake error messages mean?

2016-06-16 Thread Howard Rubin
 

CMake is giving many error messages like the below since we added OpenCV
3.1.0 to our project (and we need that new version). Can anyone help me
understand what do about it and/or what the error messages are telling me?

 

None of the 3 hits for this google search were helpful: opencv cmake "which
is prefixed in the"

[CMake] Relative path to CMAKE_SOURCE_DIR

2015-10-09 Thread Howard Rubin
Is it possible to get the relative path from PROJECT_BINARY_DIR (or
CMAKE_BINARY_DIR) to CMAKE_SOURCE_DIR?

 

I'm using CMAKE_SOURCE_DIR to add files to *.csproj file (copied with
configure_file) using CMake on Windows. This results in lots of warnings
like the below that I'd like to get rid of. If I change the absolute path
that's inserted by CMake's substitution of CMAKE_SOURCE_DIR to a relative
path with dots (e.g. ..\..\somewhere) the warning goes away.

 

Warning   43   The file
'D:/directory1/directory2/directory3\directory4\Open-XML-SDK\DocumentFormat.
OpenXml\src\Framework\AlternateContent.cs' could not be added to the
project.  The specified path contains invalid characters, is an absolute
path, or is a path outside of the project directory. DocumentFormat.OpenXml

[CMake] How to use lib from include_external_msproject

2015-08-20 Thread Howard Rubin
I have a C++/CLI LIB (and DLL) that I generate with
include_external_msproject. I need to link to it from my C++ project, which
I'm trying to do with target_link_libraries. This gives the below error
message. Since I'm not creating it with add_library I don't see how to
indicate it's a shared lib.

 

How can I indicate the lib is a SHARED lib, or otherwise link to it in a
CMake project?

 

 

CMake Error at modules/PptxWriterCpp/sample/CMakeLists.txt:4
(target_link_libraries):

  Target "PptxWriterCpp" of type UTILITY may not be linked into another

 target.  One may link only to STATIC or SHARED libraries, or to executables

  with the ENABLE_EXPORTS property set.
