Re: [CMake] how to modify scope of imported library

I just did the same thing as Petr,

Hopefully, we can do it gracefully with 2.8.8.

Thanks~~

[CMake] how to modify scope of imported library

[Cong Ma]

Hi,

Imported library has scope in the directory in which it is created and
below.

If I want to use this library in parent scope, what should I do?

for example,

top CMakeLists.txt

add_subdirectory(sub)
add_executable(myapp main.cpp)
target_link_libraries(myapp imported_lib)

sub CMakeLists.txt

add_library(imported_lib STATIC IMPORTED)

Thanks for your helping~~
