Is there an easier way to pass properties from one ExternalProject_Add command
to another?
The only way I've got it to work is..
1) Use the command "ExternalProject_Add(myExternalDependencyA ...)"
2) Use "add_library(imported_myExternalDependencyA STATIC IMPORTED)"
3) Get "ExternalProject_Get_Property(myExternalDependencyA install_dir)"
4) Use "set_target_properties(imported_myExternalDependencyA
INCLUDE_DIRECTORIES ${install_dir}/include" and any other properties etc..
5) Use the command "ExternalProject_Add(myExternalDependencyB ...
CMAKE_ARGS -DMY_EXTERNAL_DEPENDENCY_A_INCLUDE= $<TARGET_PROPERTY:
imported_myExternalDependencyA,INCLUDE_DIRECTORIES>)"
It seems to work but it also seems excessive. Is there a better way that
doesn't require using an imported library? $<TARGET_PROPERTY:TARGET,PROPERTY>
doesn't seem to work with ExternalProjects.
