hello CMake community,
I am experimenting with external projects. I have some files in an
external project which are generated in `${CMAKE_SOURCE_DIR}`.
When I add the external project, however, it is using
`${CMAKE_SOURCE_DIR}` of the external project.
I need `${CMAKE_SOURCE_DIR}` to be relative to the "super build",
instead of the external project path.
Example:
/message("${CMAKE_SOURCE_DIR} = /home/user/super")//
//
//ExternalProject_Add(ext1//
// # directory options//
// SOURCE_DIR "${CMAKE_SOURCE_DIR}/ext1"//
//)/
${CMAKE_SOURCE_DIR}/ext1/CMakeLists.txt:
/message("${CMAKE_SOURCE_DIR} = /home/user/super/ext1")/
The desired outcome would be to have the path /home/user/super in both
messages.
How can I do this?
thank you
