There is with cmake 3.1:
set(isExe $,EXECUTABLE>)
target_sources(legacyLib INTERFACE
"$<${isExe}:${CMAKE_CURRENT_SOURCE_DIR}/use_symbol.cpp>")
LegacyLib provides a simple source file which gets compiled into executables
linking to it, and the source file invokes the singleton or whatever.
This kind of use-case was the primary motivation for target_sources.

The actually legacy library I'm using has wrapped the global map 'm' inside a singleton which I believe resolves the static ordering issue. I currently have to specify something like the following for every application that wants to use this library target_link_libraries( Application -Wl,--whole-archive -llegacyLib -Wl,--no-whole-archive libA libB ) I was hoping there might have been a better way to do this with target properties of legacyLib. ~Adam -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
