How to port a qmake project to cmake

问题:

I would like to "port" this C++ project, which uses qmake (i.e., a Tool.pro file) for building, to cmake.

Essentially, I'm asking how to go about writing the necessary CMakeLists.txt file(s) by looking at the Tool.pro file above.

This is what I've done so far:

include_directories(../lib/cudd-2.5.0/include BFAbstractionLibrary)

add_executable(slugs BFAbstractionLibrary/bddDump.cpp BFAbstractionLibrary/BFCuddVarVector.cpp BFAbstractionLibrary/BFCudd.cpp BFAbstractionLibrary/BFCuddManager.cpp \
    BFAbstractionLibrary/BFCuddVarCube.cpp tools.cpp synthesisAlgorithm.cpp synthesisContextBasics.cpp variableManager.cpp \
    BFAbstractionLibrary/BFCuddMintermEnumerator.cpp)

add_library(lcudd ../lib/cudd-2.5.0/cudd)
add_library(ldddmp ../lib/cudd-2.5.0/dddmp)
add_library(lmtr ../lib/cudd-2.5.0/mtr)
add_library(lepd ../lib/cudd-2.5.0/epd)
add_library(lst ../lib/cudd-2.5.0/st)
add_library(lutil ../lib/cudd-2.5.0/util)

target_link_libraries(slugs lcudd, lutil, lmtr, lst, ldddmp, lepd)

This is definitely missing the headers that are present in the Tool.pro file. I'm also not sure what I have to do with the flags in the first 24 lines of the Tool.pro file.

Could you point me in the right direction please?

• PS1. I have already looked at the CMake Tutorial.
• PS2. I have tried two scripts: q2c, qmake2cmake. The former built an essentially empty CMakeLists.txt file. The latter built a seemingly OK file but then make failed saying it couldn't find some header file (which is located in a subdirectory).
• PS3. I have successfully built the project with qmake.

回答1:

After sacrificing some of the modularity and complexity of the Tool.pro file above, I was able to build the project using cmake. Here's the CMakeLists.txt file that I wrote:
