Hi, I added some ExternalProject_Add directives to my project. Each of them runs the sequence of configure, make all, make install. Later projects need run commands generated in early projects during their build phases.
Each project installs generated files at the place ${BUILD_DIR} which is set
at the top of the cmake file and passed down to the configure command. I tried
setting ENV{PATH} to include the directory ${BUILD_DIR}/bin but cmake doesn't
pass the changed environment variable down to the ExternalProject_Add
directives. Since the changed environment isn't passed down later projects
don't look for generated commands in ${BUILD_DIR}/bin.
How can I pass down the PATH environment to ExternalProject_Add?
CMakeLists.txt:
set(BUILD_DIR "${CMAKE_CURRENT_BINARY_DIR}/build")
set(ENV{PATH} "${CMAKE_CURRENT_BINARY_DIR}/build/bin")
ExternalProject_Add(project0
CONFIGURE_COMMAND ./configure --prefix=${BUILD_DIR}
BUILD_IN_SOURCE 1
)
ExternalProject_Add(project1
DEPENDS project0
CONFIGURE_COMMAND ./configure --prefix=${BUILD_DIR}
BUILD_IN_SOURCE 1
)
