Re: [boost] [CMake proto] `make test` almost `ctest` but CMake DEPENDS not working (was: ctest, not make, (as documented) needed to run tests

The following comments:

#     makefiles. Use "make" to build, "make test" to test, "make         #
#     install" to install, and "make package" to build binary            #

in the top-level CMakeLists.txt indicate that last conclusion
about having to run ctest is wrong.  I tried `make test` and
the output, indeed, showed test drivers were being compiled.
However, I had done a `make clean` and turned every BUILD_BOOST_library
option in CMakeCache.txt OFF.  Now, as reported previously, it's
not finding the libraries.  At first, it couldn't find the
unit_test_framework library:

[  5%] Built target boost_iostreams-shared
Linking CXX executable ../../../bin/tests/iostreams/array_test
/usr/bin/ld: cannot find -lboost_unit_test_framework-shared
collect2: ld returned 1 exit status

However, after turning that ON, I got:

/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../lib/crt1.o: In function 
`_start':
../sysdeps/i386/elf/start.S:115: undefined reference to `main'
collect2: ld returned 1 exit status

So then I tried:

BUILD_STATIC:BOOL=ON

and this got further:

Linking CXX executable ../../../bin/tests/iostreams/regex_filter_test
/usr/bin/ld: cannot find -lboost_regex-static
collect2: ld returned 1 exit status
make[2]: *** [bin/tests/iostreams/regex_filter_test] Error 1
make[1]: *** [libs/iostreams/test/CMakeFiles/regex_filter_test.dir/all] 
Error 2
make: *** [all] Error 2

So I looked at the iostreams test/Jamfile.v2 which showed 
regex_filter_test requiring boost_regex:

           [ test-iostreams
                 regex_filter_test.cpp
                 /boost/regex//boost_regex ]

The corresponding line in iostreams test/CMakeLists.txt has:

boost_test_run(regex_filter_test
   DEPENDS boost_unit_test_framework boost_regex
   COMPILE_FLAGS "-DBOOST_IOSTREAMS_NO_LIB")

but, apparently, the DEPENDS in the above boost_test_run macro
call does not cause boost_regex library to be built and loaded
to create the iostreams regex_filter_test.

Anyone have any suggestions about how to solve this?

TIA.

Larry
