I'm having an issue building a child project through my master project where the child project is an "External Project" which is automatically built using CMake's "ExternalProject_Add" feature if it is not found (using "FindChildProject.cmake"). The error message happens during installing of the child project after running my cmake and make command.

Do I need to modify the RPATH settings from the master project or how can I specify the order of installation such that the libs are installed before the bin? The static library, libdawg2.a, which is trying to be linked to the executable in the error message above, is built in "/home/hendrix/repo/spartaabc-personal/build/ext_deps/ext_dawg-build/src/lib", but is installed to "/home/hendrix/repo/spartaabc-personal/build/ext_deps/ext_dawg-build/lib" where the executable in "/home/hendrix/repo/spartaabc-personal/build/ext_deps/ext_dawg-build/bin" needs to set it's RPATH. And like I said I can build this child project alone, it's RPATH is set to "<CMAKE_INSTALL_PREFIX>/lib" in it's respective CMakeLists.txt file. -- Zach Mertens zmert...@asu.edu
