No, you don't have to.


Do you want to build static and dynamic lib at the same time ?
Then do something like this ?

add_library(foo STATIC ${libSrcs})
add_library(fooShared SHARED ${libSrcs})

set(myLibs foo)

if (USER_DECIDED_TO_LINK_AGAINST_SHARED_LIBS)
  set(myLibs fooShared)
else()
  set(myLibs foo)
endif()


add_executable(hello ${hellosSrcs})

target_link_libraries(hello ${myLibs} )
