How to link a Wt with project via cmake when Wt is built from source (MSVC2015)?
Added by Aleksey Anosov over 6 years ago
Hello! I am trying to link Wt library via cmake. I've already compiled Boost and Wt libraries like in tutorial. My CMakeLists.txt:
cmake_minimum_required( VERSION 2.8 )
project( Wt_cmake_test )
SET( CMAKE_MODULE_PATH "c:/Wt/wt-3.3.8/cmake" )
SET( CMAKE_BIULD_TYPE Debug )
FIND_PACKAGE( Wt REQUIRED )
INCLUDE_DIRECTORIES( ${Wt_INCLUDE_DIR} )
TARGET_LINK_LIBRARIES( ${PROjECT_NAME}
${Wt_DEBUG_LIBRARY} # or {Wt_LIBRARY}
${Wt_HTTP_DEBUG_LIBRARY} # or {Wt_HTTP_LIBRARY}
${Wt_EXT_DEBUG_LIBRARY} # or {Wt_EXT_LIBRARY}
)
add_executable(${PROJECT_NAME} "main.cpp")
I tryed to build project but got the error message:
Execution "C:\Program Files\CMake\bin\cmake.exe -E server "---pipe=\\.\pipe\{b727f4e5-83f8-4bc5-a1b2-f2965bf06c83}\" ---experimental\" in C:\Users\g_r_e\AppData\Local\Temp\QtCreator-l9Mfi9\qtc-cmake-XXUVjXAB.
CMake Error at C:/Wt/wt-3.3.8/cmake/FindWt.cmake:149 (MESSAGE):
Could NOT find Wt
Call Stack (most recent call first):
CMakeLists.txt:9 (FIND_PACKAGE)
Configuring incomplete, errors occurred!
What am I doing wrong? How to link it?

I have the same problem when I use MinGW.

Hey aleksey,
The FindWt module was contributed, personally I don't use it. It's possible that it does not work on Windows. I usually set Wt_INCLUDE_DIR and all the wt libraries manually.
In Wt 4, we use a newer method of generating the import modules, which should work on windows too.
Best regards,
Wim.

Thanks, Wim.

I am running into problems too, i just did take the "Hello World" example from EmWeb-Homepage (https://www.webtoolkit.eu/wt/doc/tutorial/wt.html) to my Windows 7 PC, put it in Codelite IDE, using MinGW64 for compile.
I did add the path to wt (4.3.1 - 64bit) include and lib folders and add wt and wthttp to the linker libraries and set compiler option std=c++14.

I just add to the main.cpp:
#include <Wt/WApplication.h>
These resolves error described before, but now i get these errors:

Ok sorry, in the posts before i did use mingw32 instead of mingw64, but now i tried again with ming64 and also did add the following includes:
#include <Wt/WEnvironment.h>
#include <Wt/WString.h>
Results still not ok:

RE: How to link a Wt with project via cmake when Wt is built from source (MSVC2015)? - Added by Heiner Bensemer almost 4 years ago
I did give it a try on CentOS7 Linux and wondering me, there is the same problem.....but i did find out, that here the problem is that i did use VCS (Visual Studio Code) as IDE for the first time and VCS did not handle the LD_LIBARY_PATH. The Solution is to parametrize your build configuration within tasks.json and at the needed path and libs to the args section like this:
"args": [
......
"-L.",
"-L/usr/local/lib",
"-lwtd",
"-lwthttpd"
Hope, this will help someone:-) It is working for me now.
RE: How to link a Wt with project via cmake when Wt is built from source (MSVC2015)? - Added by Heiner Bensemer almost 4 years ago
One more hint - do not parametrize the environment like hat, it has no reflect for loading libs:
"environment": [{ "name": "LD_LIBRARY_PATH", "value": "/usr/local/lib" }],
