I tried to do that following your suggestions. So I now bundled up
FindLua51.cmake in the plplot source directory and tried to do a build
after the suggested modifications. So the file FindLua51.cmake in the
directory cmake/modules has this:-
===================================
FIND_PATH(LUA_INCLUDE_DIR lua.h
HINTS
$ENV{LUA_DIR}
PATH_SUFFIXES include/lua52 include/lua5.2 include/lua51
include/lua5.1 include/lua include
PATHS
~/Library/Frameworks
/Library/Frameworks
/usr/local
/usr
/sw # Fink
/opt/local # DarwinPorts
/opt/csw # Blastwave
/opt
)
FIND_LIBRARY(LUA_LIBRARY
NAMES lua52 lua5.2 lua-5.2 lua51 lua5.1 lua-5.1 lua
HINTS
$ENV{LUA_DIR}
PATH_SUFFIXES lib64 lib
PATHS
~/Library/Frameworks
/Library/Frameworks
/usr/local
/usr
/sw
/opt/local
/opt/csw
/opt
)
===============================
However the build still fails with the following messages:-
===============================
CMake Error at cmake/modules/FindLua51.cmake:69 (INCLUDE):
include could not find load file:
/home/abuild/rpmbuild/BUILD/plplot-5.9.9/cmake/modules/FindPackageHandleStandardArgs.cmake
Call Stack (most recent call first):
cmake/modules/lua.cmake:63 (find_package)
cmake/modules/plplot.cmake:475 (include)
CMakeLists.txt:91 (include)
-- Found Lua51: /usr/lib64/liblua.so;/usr/lib64/libm.so
-- LUA_VERSION = 5.2
-- WARNING: Lua executable found but version not consistent with
library. Disabling Lua bindings
===============================
I am sure I am doing something wrong, but can't quite figure it out.

Thanks for your extensive help.
