CMakeBuildDeps

Build library dependencies from anywhere in the source tree.

If you already have all your libraries under your project root, you don't need this.

Manifest Utils

include(/path/to/ManifestFile)

Add a library from anywhere in the source tree, only once, as a "subdirectory"

function(builddep_find_lib lib_name)
# Already loaded?
get_property(${lib_name}_defined_globally GLOBAL PROPERTY global_${lib_name}_loaded DEFINED) 

if(NOT ${lib_name}\_defined\_globally)  
    define_property(GLOBAL PROPERTY global_${lib_name}_loaded   
        BRIEF_DOCS "Boolean variable indicating whether a lib was loaded"  
        FULL_DOCS "See Brief Docs")  
    set_property(GLOBAL PROPERTY global_${lib_name}_loaded FALSE)  
endif(NOT ${lib_name}\_defined\_globally)  

get_property(${lib_name}\_loaded GLOBAL PROPERTY global\_${lib_name}_loaded)  

# Use the two arg form of add\_subdirectory to specify the binary\_dir for the dependency  
if(NOT ${lib_name}_loaded)  
    set_property(GLOBAL PROPERTY global_${lib_name}_loaded TRUE)  
    string(TOUPPER ${lib_name} lib\_name\_upper)  
    add_subdirectory(${${lib\_name\_upper}\_IMPORT\_DIR} ${CMAKE\_BINARY\_DIR}/${lib_name})  
endif(NOT ${lib_name}_loaded)

endfunction()

Add just the library's public includes.

Only needed to handle circular header deps.

function(builddep_target_add_headers target_name scope lib_name)
string(TOUPPER ${lib_name} lib_name_upper)
target_include_directories(${target_name} ${scope} ${${lib_name_upper}_IMPORT_DIR}/include)
endfunction()
