I am using CMake 3.15.1. Having found out about some of the changes with
3.13, I've started to take advantage of using 'add_subdirectory()' in
certain cases when a module is large and spans multiple source folders.
For instance:
ModuleA/CMakeLists.txt:
------------------------------------
add_library(moduleA STATIC "")
add_subdirectory(sub1)
add_subdirectory(sub2)
------------------------------------------
sub1/CMakeLists.txt
------------------------------
target_include_directories(moduleA PUBLIC .)
target_sources(moduleA
PRIVATE
src1.cpp
src2.cpp
)
target_link_libraries(moduleA
PRIVATE
Qt5::Widgets
Qt5::Qml
moduleB
)
sub2/CMakeLists.txt
------------------------------
target_include_directories(moduleA PUBLIC .)
target_sources(moduleA
PRIVATE
src1.cpp
src2.cpp
)
target_link_libraries(moduleA
PRIVATE
Qt5::Quick
moduleC
)
-----------------------------------
I run cmake --graphviz=project.dot .
>From this, two of the files that comes out are project.dot.moduleA and
project.dot.moduleA.dependers.
The former is only this:
digraph "GG" {
node [
fontsize = "12"
];
"node190" [ label="moduleA" shape="diamond"];
}
There is no mention of the Qt5 or other module dependencies.
Other modules with dependencies but without the hierarchy introduced with
add_subdirectory() seem to be just fine and include their respective
dependencies in their project.dot.moduleX files.
Is this a bug or am I misusing add_subdirectory() here? With the exception
of the graphviz output, everything builds and runs as expected with my
setup.
