Summary0015756: FindLua.cmake doesn't work when both Lua5.2 and Lua5.3 are installed.
DescriptionIf you call find_package(Lua 5.2 REQUIRED) or find_package(Lua REQUIRED) this happens:

Found Lua: /usr/lib64/liblua5.2.so;/usr/lib64/libm.so (found suitable version "5.3.1", minimum required is "5.2")

Basically the 5.2 library is found but it still uses the 5.3 include path, hence the wrong "suitable version":

CMakeCache.txt
LUA_INCLUDE_DIR:PATH=/usr/include
LUA_LIBRARY:FILEPATH=/usr/lib64/liblua5.2.so

Calling find_package(Lua 5.3 REQUIRED) works fine though.
Steps To Reproduce
Additional Informationlua5.3 is installed to /usr/include
lua5.2 is installed to /usr/include/lua5.2

Bug affects me too, attached file proposed as a patch to fix this.

Its try to find header file in version-specific dirs at first, and then in common dirs (and also check version from lua.h against needed version).
