Setting CMAKE_MODULES_PATH

[Akarsh Simha]

I have a question regarding CMAKE_MODULES_PATH. 

I frequently have to deal with building a branch of my project
(kdeedu/kstars), but wish to use the dependency modules (kdelibs etc)
from my trunk install.

However, my build fails with an error that says approximately:

"Could not find FindKDE4Internal.cmake in <blank>".

So I tried exporting CMAKE_MODULE_PATH, appropriately, but it didn't
work, and I attribute that to a line in kdeedu/CMakeLists.txt that
says:

set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/cmake/modules )

Shouldn't it instead read as follows?

set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/cmake/modules ${CMAKE_MODULE_PATH})

I made this change, and things built fine for me (because I'd already
exported the right CMAKE_MODULE_PATH in the environment)

So can I make this change permanent in KDE Edu's CMakeLists.txt?

It seems that there are similar statements in the CMakeLists.txt files
of other KDE modules as well.
