Summary

0000264: FIND_* needs a more general way of handling system path

Description

Basically, the FIND_PROGRAM command looks like this:

FIND_PROGRAM(CMAKE_AR NAMES ar PATHS /bin /usr/bin /usr/local/bin)
FIND_PROGRAM(CMAKE_RANLIB NAMES ranlib PATHS /bin /usr/bin /usr/local/bin)

And it works by looking in the paths specified to the command first,
then in the environment variable $PATH. So, you get the bad behavior
where cmake made find something not in your path.

One option to fix this would be to change the order, so that FIND_PROGRAM
looks in the PATH first then in the other paths passed into the command.
However, this may produce different results than cmake has in the past.
A better option would be to specifically ask for the system path in the command,
so cmake list writers could decide where to put the path.

Something like this:

FIND_PROGRARM(CMAKE_AR_NAMES ar PATHS SYSTEMPATH /bin /usr/bin /usr/local/bin)

You could not use $ENV(PATH) because path can be ; or : separated depending on the OS.

Perhaps all the FIND_* stuff should be generalized.
