[CMake] external project CONFIGURE_COMMAND adds quotation to arguments

[Edoardo Pasca]

Dear all,

I'm using ExternalProjectAdd to build an external package.

On the CONFIGURE_COMMAND I have to pass some variables to the configure
script in this form:

configure CPPFLAGS="-I/dir/include -L/dir/lib"

To do this I use

CONFIGURE_COMMAND ${CMAKE_COMMAND} -E env ${CMAKE_BINARY_DIR}/configure
CPPFLAGS="-I/dir/include -L/dir/lib"

However, when cmake issues that command (you can see that with make
VERBOSE=1) it wraps the CPPFLAGS parameters with quotation marks (as below)
and the configure script fails

configure "CPPFLAGS=\"-I/dir/include -L/dir/lib\""

Below you can find a minimal CMakeLists.txt to test this.

I'd appreciate any help on how I'd remove those quotation marks.

Thanks

Edo
