If you need to set build time ENV vars, how about this?
# build.cmake:
set(ENV{WEBSOCKETPP_INSTALL_TO_ARTIFACTS} "install")
execute_process(COMMAND make -f Makefile $ENV{WEBSOCKETPP_INSTALL_TO_ARTIFACTS})
and then:
ExternalProject_Add( ...
BUILD_COMMAND ${CMAKE_COMMAND} -P ${CMAKE_CURRENT_SOURCE_DIR}/build.cmake
...
)
That's the only presently reasonable way to set ENV vars during an
ExternalProject build step.
