I'm running Fedora 25 and this bug is still present.

$ rpm -q mingw64-filesystem
mingw64-filesystem-101-1.fc25.noarch

+++ This bug was initially created as a clone of Bug #1152696 +++

Description of problem:
The mingw{32,64}-cmake command uses absolute paths to specify certain locations. If the cmake configuration honors these paths then it breaks CPack which does a fake install for packaging purposes.

Version-Release number of selected component (if applicable):
mingw32-filesystem-99-3.fc20.noarch

Actual results:
An error is generated:
Run CPack packaging tool...
/usr/bin/cpack --config ./CPackConfig.cmake
CPack: Create package using NSIS
CPack: Install projects
CPack: - Run preinstall target for: codec2
CPack: - Install project: codec2
CMake Error at /home/build/mingw32/codec2/src/cmake_install.cmake:37 (message):
  ABSOLUTE path INSTALL DESTINATION forbidden (by caller):
  /usr/i686-w64-mingw32/sys-root/mingw/lib/libcodec2.dll.a

Expected results:
Package is created correctly.

Additional info:
The main problem seems to be CMAKE_INSTALL_LIBDIR...
