<p class="MsoNormal"><span lang="EN-US">We are using CMake to build an open source project. We would like to build it on Windows. For that purpose, we use MingW.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">However, we have trouble linking three libraries :<o:p></o:p></span></p>
<ul style="margin-top:0cm" type="disc">
<li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1"><span lang="EN-US">libstdc++-6.dll<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1"><span lang="EN-US">libwinpthread-1.dll<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1"><span lang="EN-US">libgcc_s_seh-1.dll
<o:p></o:p></span></li></ul>
<p class="MsoNormal"><span lang="EN-US">To solve this, we decided to link all three statically. In order to do so, we added the following to our main CMakeLists.txt [1]:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> set(CMAKE_CXX_STANDARD_LIBRARIES <b>"-static-libgcc -static-libstdc++</b> -lwsock32 -lws2_32 ${CMAKE_CSS_STANDARD_LIBRARIES}")<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> set (CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS}
<b>-Wl,-Bstatic,--whole-archive -lwinpthread</b> -Wl,--no-whole-archive")<o:p></o:p></span></p>
<p class="MsoNormal" align="center" style="text-align:center"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Is this the correct way to proceed in CMake ? Are these the right variables and flags to set ? Do we have to use two different cmake variables to achieve our goal ?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Any hints on improving this CMakeLists.txt is welcome.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks.<o:p></o:p></span></p>
