Dear all,
I have difficulties including a XYZ.cmake file from an external project.
ExternalProject_Add(MTL4
SVN_REPOSITORY https://simunova.zih.tu-dresden.de/svn/mtl4/trunk
SVN_USERNAME guest
SVN_PASSWORD guest
SVN_TRUST_CERT 1
TIMEOUT 180
PREFIX ${CMAKE_BINARY_DIR}/external/MTL4
CONFIGURE_COMMAND ""
BUILD_COMMAND ""
INSTALL_COMMAND “"
)
ExternalProject_Get_Property(MTL4 source_dir)
set(MTL4_INCLUDE_DIRS ${source_dir})
set(MTL_DIR ${source_dir})
# Include MTLConfig from the unpacked(!!!) MTL4 library
include("${source_dir}/MTLConfig.cmake" OPTIONAL RESULT_VARIABLE
MTLCONFIG_FOUND)
# MTL4 is a header-only library, hence downloading and unpacking is sufficient
add_executable (demo demo.cxx)
add_dependencies(demo MTL4)
The problem is, that in a fresh build the MTL4 library is not yet unpacked, and
hence, the MTLConfig.cmake file is not available.
How can I “include(…)” a cmake file which is only available after the external
project has been processed?
Kind regards,
Matthias
