Are you trying to construct a BUILD_COMMAND line that looks like
CXXFLAGS=-g -02 -w && ./configure?
If so, you should be able to do that with the CMake -E env command option
like this ( Starting in CMake 3.1 ):
set(cxx_flags "-g -O2 -w")
set(command_to_run ${CMAKE_COMMAND} -E environment)
ExternalProject_Add(MyProject
DOWNLOAD_COMMAND ""
CONFIGURE_COMMAND ""
BUILD_COMMAND ${CMAKE_COMMAND} -E env CXXFLAGS=${cxx_flags}
${command_to_run}
)
