I work on Torch ebuilds in my overlay. And got into situation which is quite easy to fix, but to me question which solution is correct.

When I install Torch package I do it as:
DESCRIPTION="Torch is a Lua-based suite for scientific computations based on multidimensional tensors."

src_configure() {
   local mycmakeargs=(
      "-DLUADIR=$($(tc-getPKG_CONFIG) --variable INSTALL_LMOD $(usex luajit 'luajit' 'lua'))"
      "-DLIBDIR=$($(tc-getPKG_CONFIG) --variable INSTALL_LIB $(usex luajit 'luajit' 'lua'))"
      "-DLUA_BINDIR=$($(tc-getPKG_CONFIG) --variable INSTALL_BIN $(usex luajit 'luajit' 'lua'))"
      "-DLUA_INCDIR=$($(tc-getPKG_CONFIG) --variable INSTALL_INC $(usex luajit 'luajit' 'lua'))"
      "-DLUA_LIBDIR=$($(tc-getPKG_CONFIG) --variable INSTALL_CMOD $(usex luajit 'luajit' 'lua'))"
      "-DSCRIPTS_DIR=$($(tc-getPKG_CONFIG) --variable INSTALL_BIN $(usex luajit 'luajit' 'lua'))"
      "-DLUALIB=`equery files luajit |grep lib64/libluajit | grep .so | awk 'NR==0; END{print}'`"


Important is my configuration of LUA libraries. With these settings Torch is installed as following:
 * QA Notice: The following shared libraries lack a SONAME
 * /usr/lib64/

strip: x86_64-pc-linux-gnu-strip --strip-unneeded -R .comment -R .GCC.command.line -R

So some goes directly to /usr/lib64 and some goes to lua subdir, which looks correct to me.

Next I am emerging ebuild for Facebook TH++ library based on Troch using CMAKE as well, but this time the library build fails on:
CMake Error at /usr/share/cmake/torch/TorchExports.cmake:70 (message):
  The imported target "TH" references the file


  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained


  but not all the files it references.

Call Stack (most recent call first):
  /usr/share/cmake/torch/TorchConfig.cmake:29 (INCLUDE)
  CMakeLists.txt:26 (FIND_PACKAGE)

So how to best result the situation by not making things dirty? (I know I can do simple symlink now and end of story..)

Thank you for suggestions.
