+Subject: [PATCH] lua.pc.in: add INSTALL_{L,C}MOD variables
+
+Note:
+
+Most distributions are defining INSTALL_LMOD and INSTALL_CMOD within their
+packaged pkg-config file of lua, because both are commonly used by third-party
+Makefiles for figuring out where to install lua modules through pkg-config.
+
+INSTALL_LMOD defines the path where to install pure lua modules
+INSTALL_CMOD defines the path where to install compiled lua modules
