[CMake] CPack: Packaging debug and release configurations in a single zip

[Patrick Johnmeyer]

Here's a follow-up.

I was unable to get Jean-Christophes modification of Ansis' solution
working. (I definitely did not want to repeat the install directives in
this rather large project.) The "-DCMAKE_BUILD_TYPE" lines don't really
accomplish anything when building with Visual Studio. I was making progress
but ultimately gave up. Here is where I stopped.

#####
include(ExternalProject)

ExternalProject_Add(MyProjectDebug
  PREFIX Debug
  SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}
  CMAKE_ARGS -G ${CMAKE_GENERATOR} -D CMAKE_BUILD_TYPE=Debug -D
CPACK_BUILD_CONFIG=Debug
  BUILD_COMMAND "${CMAKE_COMMAND}" --build
${CMAKE_BINARY_DIR}/Debug/src/MyProjectDebug-build --config Debug
  )

ExternalProject_Add(MyProjectRelease
  PREFIX Release
  SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}
  CMAKE_ARGS -G ${CMAKE_GENERATOR} -D CMAKE_BUILD_TYPE=Release -D
CPACK_BUILD_CONFIG=Release
  BUILD_COMMAND "${CMAKE_COMMAND}" --build
${CMAKE_BINARY_DIR}/Release/src/MyProjectRelease-build --config Release
  )


set(CPACK_INSTALL_CMAKE_PROJECTS
  "${CMAKE_BINARY_DIR}/Debug/src/MyProjectDebug-build;MyProject;ALL;/"
  "${CMAKE_BINARY_DIR}/Release/src/MyProjectRelease-build;MyProject;ALL;/"
)

include(CPack)
#####

At this point, the debug build would build in the debug tree and the
release build in the release tree. All is well to that point. However, when
I would attempt to use CPack with no -C option it would attempt to package
Debug from the Release tree. When I would attempt to use CPack with a -C
option, it would fail on one or the other (whichever one I did not specify).

I tried a slight fork of the above using the NMake generator instead of the
Visual Studio 10 generator but still ran into some issues local to our
CMake files. I may try to resolve that next, but if anybody has any hints
of where go from here that would be appreciated.

Frankly it seems to me that we should be able to package multiple configs
without any of this extra work.
