Re: [CMake] build order

Hi David

Thank you for the response, I thought that I was doing something wrong. I
mean it's documented and I followed the docs as close as possible to write
my scripts but there's literally no mention about how to solve this
external/ internal project setup in the official docs.

I saw some things online but I honestly it seemed overly complicated and
really prone to breaking.

I'll edit my project to make them all external projects and work from that
angle.

Thanks

Re: [CMake] build order

Build the second thing as an ExternalProject, too, and use the DEPENDS keyword 
to make it build after the first thing.

Don't try to mix-and-match external projects and non-external projects in the 
same CMake configure... It's just too much work to get things working in a 
reasonable cross-platform way. It's possible, but certainly not easy.

[CMake] build order

2015-12-18 Thread Owen Hogarth II 
If you download, compile and install a cmake project through external
project

How can I make sure that the external project is built before something
that depends on that external project?

[CMake] Build order

2011-06-27 Thread Maxime Lecourt 
Hello,

I'm using CMake to build OCaml libraries.
For that, I use a macro that I call in my CMakeLists.txt

As I have dependencies between my different libraries, I wrote my
CMakeLists.txt so the build happens in the right order, but when building,
libraries are built depending on alphabetical order.

add_ocaml_library(cabs SOURCES cabs.ml)
add_ocaml_library(algo SOURCES algo.ml)

(algo depends on cabs being already built)

How can I create a add_ocaml_dependencies macro ?
Or is there a way to force CMake to follow the build order in the
CMakeLists.txt ?

Regards

Maxime Lecourt

Well, if cabs and algo are top-level targets (i.e. created via
add_library(), add_executable() or add_custom_target()), you can simply
call add_dependencies(algo cabs).

algo and cabs are created using add_custom_command()

I tried add_dependencies(algo cabs), but it did not work.
Would it work if i create a fake target (can I force cabs and algo as
top-level targets, or as valid parameters for add_custom_target ?) ?

add_custom_target(target1 depends cabs)
add_custom_target(algo depends target1)


Or something like that.

Yes, you should create a custom target with add_custom_target(). In
CMake you have to distinguish between top-level and file-level targets.
add_custom_command() only creates a file-level target, so you need the
add_custom_target() call. Also, this will make it possible to build the
targets selectively from the command line or the IDE.

However, your above shown code is semantically wrong. Your
add_ocaml_library() macro (you probably should make it a function
instead) should contain the add_custom_target() call and give it the
name passed to the add_ocaml_library function.

[CMake] Build-order in Visual Studio

2009-01-26 Thread Micha Renner 
Hello,

is it possible to influence the build-order of MSVC from
CMakeLists.txt-files?

The top-level CMakeLists.txt looks like this:

ADD_SUBDIRECTORY(lib1)
ADD_SUBDIRECTORY(lib2)
ADD_SUBDIRECTORY(lib3)
ADD_SUBDIRECTORY(lib4)
ADD_SUBDIRECTORY(prog)

prog depends on the libs. lib3 depends on lib1 and lib4 depends on lib2.
After a cMake-run the build-order in Visual Studio is pure random,
even the main-program is sometimes ZERO_CHECK.

 Use target_link_libraries and add_dependencies to fix project build
 order.
 

I think, that this doesn't work in the case here.
For target_link_libraries I need a library. If prog is first in build
process then there are no libs.
add_dependencies helps if all projects would be in one CMakeList-file.
