[CMake] gathering directory names in cmake

[Lee Butler]

Alas, this has no effect.  Consider the following shell script:

-----------------------------------------------------------------
#!/bin/sh
if [ -d attempt ] ; then rm -rf attempt ; fi
mkdir attempt
cd attempt
for d in src src/app src/plugins/one ; do
     mkdir -p $d/xyz
     touch $d/xyz/one.txt
     touch $d/xyz/two.txt
done
PATTERN="\${CMAKE_SOURCE_DIR}/src/*xyz/"

cat > CMakeLists.txt <<EOF
project(gatherdir)
cmake_minimum_required(VERSION 3.0)

file(GLOB_RECURSE xyzDirs "${PATTERN}")
message(STATUS "____look for ${PATTERN}")
message(STATUS "____xyzDirs: \${xyzDirs}")
EOF
cmake .
---------------------------------------------------------------------
I cannot find any string that PATTERN can be which will cause xyzDirs to 
have the names of the three "xyz" directories.  I could search for 
*xyz/* but now I have to edit the list to remove file names, remove 
doubles from the result, etc.
