I have just started using some externally supplied cmake projects in my
cmake project. To do this I added these lines to my top level
CMakeLists.txt file:
include(ExternalProject)
ExternalProject_Add(external_proj
PREFIX ${CMAKE_BINARY_DIR}/external_proj
SOURCE_DIR ${CMAKE_SOURCE_DIR}/external/proj/dir
CMAKE_ARGS -DCMAKE_BUILD_TYPE:STRING=Release
-DMETAGS_DIR=${CMAKE_BINARY_DIR}/meta_install
INSTALL_COMMAND ""
)
And that worked very well. Inside Visual Studio when I build my project it
automatically runs the cmake configure step for the external projects and
builds them as well. The problem I have just discovered is when using a
build configuration other than the default ones. I can build Debug and
Release configurations fine. My project also has a DebugOptimised
configuration but the external projects don't. When I try to build my
project it fails to build the external projects. I used build_command() to
see what commands would be used to build each configuration and I can see
the cause of the problem:
Debug: VCExpress.exe myProj.sln /build Debug /project
external_proj
DebugOptimised: VCExpress.exe myProj.sln /build DebugOptimised /project
external_proj
Is there a way to tell cmake how to map my build configurations onto those
that an external project has ? In this case I would like to build the
external project as Debug when I am building my project as DebugOptimised.
