Thanks.  I started with a change to simplify the test infrastructure slightly:

 Tests: Simplify GeneratorExpression check implementation
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=7de868c4

Then I applied your changes with minor tweaks and merged to 'next'
for testing:

 Genex: Add a SHELL_PATH expression
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=8adf6ab5

I left out the ExternalProjectShellPathGenex test because it fails
on the Ninja, MSYS Makefiles, and MinGW Makefiles generators on
Windows.  The 'pushd' and 'popd' commands do not work there due to
the way the build tool runs the command in a shell.  It passed for
me only in a VS IDE generator.  See also David Cole's sibling
response about this test.
