No problem
I add some other info I hope it helps
- you don't need to set DEVKIT_LOCATION when you defined them in your env
vars or batch file
- this is wrong: set(ENV{DEVKIT_LOCATION}
"${CMAKE_SOURCE_DIR}/external/devkitBase")
- ENV will be used when you defined your env var outside of the
CMakeLists.txt so in this case you just need to use it like: $ENV{
DEVKIT_LOCATION}
- for Qt dependencies I told you you should use
find_package(Qt5 COMPONENTS Core Widgets Gui OpenGL REQUIRED)
target_link_libraries($ENV{TARGET_NAME} Qt5::Core Qt5::Widgets Qt5::Gui
Qt5::OpenGL)
- you don't need to add CMAKE_MODULE_PATH to your CMakeLists.txt file
however, (I forgot to mention) you should define this env var
set Qt5_DIR=%SDKS_LOCATION%/Qt5/lib/cmake
in your windows env var or your build.bat file
- if you want to have multithreaded things, instead of
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /MT")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} /MT")
you can use this
set(CMAKE_MSVC_RUNTIME_LIBRARY "MultiThreadedDLL")
this is my DEVKIT_OCATION
in batch file:
set SDKS_LOCATION=D:/myPath/sdks
set DEVKIT_LOCATION=%SDKS_LOCATION%/Maya_2019
in CMakeListx.txt file:
include($ENV{DEVKIT_LOCATION}/cmake/pluginEntry.cmake)
- at the end, you don't need to set things like:
CMAKE_MODULE_PATH
MAYA_INCLUDE_DIR
MAYA_LIBRARIES
all of these settings will be managed automatically
you just need to have a cleaner CMakeLists.txt file and do things based on
this order:
1. in *build.bat: * call the vcvarsall.bat
@REM VCVARS_LOCATION: C:\Program Files\Microsoft Visual
Studio\2022\Community\VC\Auxiliary\Build
call "%VCVARS_LOCATION%/vcvarsall.bat" x64
2. in *build.bat: *Set your env Variables like :QT_DIR, DEVKIT_LOCATION, ...
3. in *build.bat: *call the cmake command from inside build directory
cd build
cmake -G "Visual Studio 17 2022" -A x64 ..
4. in *CMakeLists.txt*: active the maya module finder:
include($ENV{DEVKIT_LOCATION}/cmake/pluginEntry.cmake)
5. in *CMakeLists.txt*: turn on Automatic builder of QT
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)
6. in *CMakeLists.txt: *Set your Project files and your libraries, or maya
libraries like *OpenMaya*, *Foundation*
7. in *CMakeLists.txt: *call this function of maya cmake module:
build_plugin()
8. in *CMakeLists.txt: *adding Qt related dependencies:
find_package(Qt5 COMPONENTS Core Widgets Gui REQUIRED)
target_link_libraries($ENV{TARGET_NAME} Qt5::Core Qt5::Widgets Qt5::Gui)
I hope it is detailed enough
this is the way I usually work, there are lots of ways to build softwares,
all experimental and true, just need to follow errors! let us know if you
need more data
cheers
