[CMake] cmake integration

[Pavel Volkovitskiy]

Hello!

I'm trying to implement initial cmake support for conary
(distributed software management system, http://wiki.rpath.com/wiki/Conary)
PS: Note, i'm not official developer of it

right now it has good support for configure based applications

let's for example we have "foo" application which uses configure script
so we will write in foo.recipe:

r.Configure('--extra-arg')

and this will translate into real ./configure call:
===================================
cd /home/int/conary/builds/foo/foo-1.2.3/; \
CLASSPATH="" CFLAGS="-O2 -g" CXXFLAGS="-O2 -g " CPPFLAGS="" LDFLAGS="-g" 
CC=gcc CXX=g++  \
./configure \
    --prefix=/usr \
    --exec-prefix=/usr \
    --bindir=/usr/bin \
    --sbindir=/usr/sbin \
    --sysconfdir=/etc \
    --datadir=/usr/share \
    --includedir=/usr/include \
    --libdir=/usr/lib64 \
    --libexecdir=/usr/libexec \
    --localstatedir=/var \
    --sharedstatedir=/usr/com \
    --mandir=/usr/share/man \
    --infodir=/usr/share/info \
    --extra-arg
===================================

after some reading i "translate" this into cmake call:
===================================
cd /home/int/conary/builds/foo/foo-1.2.3/; \
mkdir -p CMakeObj; cd CMakeObj;  \
CC=gcc CXX=g++  cmake \
    -DCMAKE_C_FLAGS:STRING="-O2 -g" \
    -DCMAKE_CXX_FLAGS:STRING="-O2 -g " \
    -DCMAKE_EXE_LINKER_FLAGS:STRING="-g" \
    -DCMAKE_MODULE_LINKER_FLAGS:STRING="-g" \
    -DCMAKE_SHARED_LINKER_FLAGS:STRING="-g" \
    -DCMAKE_INSTALL_PREFIX:PATH="/usr" \
    -DEXTRA_ARG=YES \
    /home/int/conary/builds/foo/foo-1.2.3/
===================================

I assume that all cmake based projects work well with out-of-source 
build (srcdir!=objdir)
Also it seems there is no standart way to specify libdir = /usr/lib or 
/usr/lib64 ?
Am I right there is no equivalent for LDFLAGS?

We prefer this to be close to configure call for convenience

Any comments?
