[CMake] override CMAKE_COMMAND

[Levy, Chen]

Hello, List.

I have CMake v2.4.7 running on SunOS 5.8 from the binary SunOS tar.gz
file, but I was unable to patch the libCrun.so.1 libCstd.so.1 on that
box.

So here what I have done:

0. I have put the CMake distributions in: /some/path/cmake

1. I have copied correct libCrun.so.1 libCstd.so.1 into
/some/path/cmake/lib

2. I have moved: /some/path/cmake/bin/cmake -> cmake.bin

3. I have created /some/path/cmake/bin/cmake like this:

  #!/bin/sh
  LD_LIBRARY_PATH=/some/path/cmake/lib /some/path/cmake/bin/cmake.bin

4. Every time I run cmake I do it like this:
/some/path/cmake/bin/cmake
-DCMAKE_COMMAND:FILEPATH=/some/path/cmake/bin/cmake

It is generally works, except when I run gmake, and it detects that the
Makefile is older then the CMakeList.txt file, in that case it runs the
${CMAKE_COMMAND} on it's own accord (without the
-DCMAKE_COMMAND:FILEPATH=/some/path/cmake/bin/cmake) and in that case
does:

...
/some/path/cmake/bin/cmake -H/path/to/objs -B/path/to/objs
--check-build-system CMakeFiles/Makefile.cmake 0
Re-run cmake file: Makefile older than: /path/to/CMakeLists.txt
-- Configuring done

-- Build files have been written to: /path/to/objs
gmake -f CMakeFiles/Makefile2 some-make-target
gmake[1]: Entering directory `/path/to/objs'
gmake[1]: *** Warning: File `CMakeFiles/Makefile2' has modification time

/some/path/cmake/bin/cmake.bin -H/path/to/objs -B/path/to/objs
--check-build-system CMakeFiles/Makefile.cmake 0
ld.so.1: /some/path/cmake/bin/cmake.bin: fatal: libCstd.so.1: open
failed: No such file or directory
...

Must I run cmake like:
/some/path/cmake/bin/cmake
-DCMAKE_COMMAND:STRING="/some/path/cmake/bin/cmake
-DCMAKE_COMMAND:FILEPATH=/some/path/cmake/bin/cmake"
And how deeply nested must I do this?

Is there a better way to override the CMAKE_COMMAND value?

Note that I must not change the LD_LIBRARY_PATH globally, because I
don't want to build with those libraries, just to run the cmake binary.

TIA,
