![]() Next, the new library target is linked to the executable target using targetlinklibraries (). When building libf, ninja only compiles f.cpp, whereas make and vs2019 first builds libd. To make use of the new library we will add an addsubdirectory () call in the top-level CMakeLists.txt file so that the library will get built.When building exec ninja seems to be able to build a.cpp, b.cpp, and c.cpp in parallel whereas vs2019 does liba, libb and exec in sequence.linklibraries is used to supply a list of libraries (object archives) to the linker. When a file is included using the pre-processor, these directories will be searched for the file. Maybe you better to make a fresh build of the Boost from the source. The named target must be created by addlibrary () within the project or as an IMPORTED library. It seems like the CMake cant locate Boost on your system. The buildsystem will have a dependency to re-link if the library file changes.Is there an intended behavior in these cases or is it up to differences in the build systems or bugs? includedirectories is used to supply a list of include directories to the compiler. A library target name: The generated link line will have the full path to the linkable library file associated with the target. Also I have observed differences in build order between ninja, make and vs2019. ![]() This includes invocations that drive compiling and those that drive linking. This property specifies the list of libraries or targets which will be used for linking. as consecutive calls to targetlinklibraries for the same target will append items in the order called. ⢠Why does building libb first build liba? As I understand it liba should just be propagated as a link time dependency to whatever actually links it in ( exec), but I realize Iâm missing something. targetlinklibraries() targetlinkdirectories() targetprecompileheaders() targetsources() CMAKEFLAGS and CMAKEFLAGS add language-wide flags passed to all invocations of the compiler.Given the example CMakeLists.txt file below I have a few questions.
