[Bf-committers] CMake Build Changes

[Campbell Barton]

@Dave, this seems to use correct permissions for python scripts, at
least blender-thumbnailer.py is executable,
Using CMake's "install(PROGRAMS ...)" command should deal with this correctly.


@Richard
For package files just add "-DWITH_INSTALL_PORTABLE:BOOL=OFF"

Example from pacman:

  cmake $blender_srcdir \
    -DCMAKE_INSTALL_PREFIX:PATH=/usr \
    -DCMAKE_BUILD_TYPE:STRING=Release \
    -DWITH_INSTALL_PORTABLE:BOOL=OFF \
    -DWITH_PYTHON_INSTALL:BOOL=OFF \
    -DWITH_OPENCOLLADA:BOOL=OFF \
    -DPYTHON_VERSION:STRING=3.2 \
    -DPYTHON_LIBPATH:STRING=/usr/lib \
    -DPYTHON_LIBRARY:STRING=python3.2mu \
    -DPYTHON_INCLUDE_DIRS:STRING=/usr/include/python3.2mu


@Ian,
This doesn't solve copying scripts problem still because its removing
the scripts before running install, this is annoying but IMHO less
annoying then users having dirs with mixed old/new scripts which we
used to get reports about in the tracker and often gave
misleading/unhelpful errors which we lost time figuring out was just
old script conflict.

If you want fast rebuilds just symlink the blender binary back to the
root source dir and don't bother "make install"
eg:
  ln -s ../cmake_debug/bin/blender ./blender_debug.bin

>From here blender find the scripts in ./release/scripts/

If there is a good way to remove all files in a dir not added by "make
install" I'd be interested to know, would be useful to run on
"/usr/share/blender/2.56/".
