I am trying to setup a pro file where I want it to only include a specific library if a variable is defined. I already have this variable passed into qmake via the command line by appending DEFINES+=VARIABLE_NAME.
I can use VARIABLE_NAME to conditionally compile parts of my code but can I have a condition to detect VARIABLE_NAME in the pro file and only include a library if it exists?
Thanks, Alan
Something like that:
DEFINES += USELIB
contains(DEFINES, USELIB) {
LIBS += SOMELIB
}
