Dear all
We have a Superbuild https://github.com/CCPPETMR/SIRF-SuperBuild. I'm trying to introduce variables to reduce duplication. However, I'm getting weird errors. 2 examples below. Any ideas? (I'm running this on Windows 10 at present with CMake 3.13.2). Many thanks Kris 1. Use of a variable for CMAKE_ARGS ExternalProject_Add(${proj} ${${proj}_EP_ARGS} GIT_REPOSITORY ${${proj}_URL} GIT_TAG ${${proj}_TAG} CMAKE_ARGS ${HDF5_CMAKE_ARGS} -DBOOST_ROOT=${BOOST_ROOT} INSTALL_DIR ${ISMRMRD_Install_Dir} With HDF5_CMAKE_ARGS=-DHDF5_ROOT:PATH=C:/Users/krisf/Documents/devel/build-VC/SIR F-SuperBuild/INSTALL -DHDF5_INCLUDE_DIRS:PATH=C:/Users/krisf/Documents/devel/build-VC/SIRF-SuperB uild/INSTALL/include -DHDF5_FIND_DEBUG:BOOL=ON Error: 5> Performing configure step for 'ISMRMRD' 5>CUSTOMBUILD : CMake error : The source directory "C:/Users/krisf/Documents/devel/build-VC/SIRF-SuperBuild/builds/ISMRMRD/buil d" does not appear to contain CMakeLists.txt. Indeed, that directory is where we sk the SuperBuild to build. The sources sit in .SIRF-SuperBuild/sources/ISMRMRD. Why does it go to the build directory? All works ok when commenting out the HDF5_CMAKE_ARGS line, or by putting its value directly in the ExternalProject_Add. 2. Use of a variable for PATCH_COMMAND find_program(GIT "git") set(PATCH_COMMAND "${GIT} apply ${PATCHFILE}") ExternalProject_Add(${proj} ${${proj}_EP_ARGS} URL ${${proj}_URL} URL_HASH MD5=${${proj}_MD5} PATCH_COMMAND ${PATCH_COMMAND} ... ) Error: 2> Performing patch step for 'HDF5' 2> The filename, directory name, or volume label syntax is incorrect. Everything works fine if I use PATCH_COMMAND ${GIT} apply ${PATCHFILE}
