Hi,

We develop a library that we will call LIBRARY. To compile this library, we use CMake \
(of course :) ). This library include multiple components, like Boost system,  i.e. \
there are few add_library commands. This library produce LIBRARY_COMPONENTS_1, \
LIBRARY_COMPONENTS_2, LIBRARY_COMPONENTS_3 (each  component is a static or shared \
library, some both). At the end, user execute "make install" to merge all include \
dirs in "include/" and all components in "lib/". This  project include a \
FindLIBRARY.cmake file to use this library in another project.

We have modules, MODULE_1, MODULE_2, ... MODULE_N. Each module use some components of \
LIBRARY, maybe LIBRARY_COMPONENTS_1,  LIBRARY_COMPONENTS_2 or both... To compile \
MODULE_1, they need to compile LIBRARY first (separately) then module CMakeLists.txt \
will use  FindLIBRARY.cmake to link to components. This one works well.

Now, we would like to make something better. We have a project PROJECT with few \
modules (not all) and we would like to compile automatically, i.e. we would  like a \
top level CMakeLists.txt which compile LIBRARY and MODULE_1, MODULE_2, MODULE_3... 

Our idea was to use add_subdirectory but modules will try to search LIBRARY and they \
will not find the library because it's not still compiled... So, how to "emulate"  \
find_package result for LIBRARY ? Bad idea (I think), is to set LIBRARY-FOUND to \
true, manually include dirs (a pain because library is not installed) and it will not \
 prevent to library upgrade (maybe that tomorrow it will have a new components, so a \
new include dir to add). 

Do you have any idea to build our top level PROJECT CMakeLists.txt ?

Thank you,

Jean
