所以在 svg.h 下包含如下： #include <boost/algorithm/string/predicate.hpp>

我有 MSVC2015 和 BOOST + FREETYPE 环境。变量被添加到系统 AND Clion。如果我从 QT 构建它，我只会得到 predicate.hpp 错误。

Answer 1

find_package(Boost REQUIRED)

# ...

# Find includes in corresponding build directories
include_directories(
        ${BOOST}
        ${FREETYPE}
        ${Qt5Widgets_INCLUDE_DIRS}
        -lopengl32 -lglu32 -luser32
)

find_package( Boost ... )设置的变量，包含Boost头文件的路径，命名为Boost_INCLUDE_DIRS，而不是BOOST。

除非 FREETYPE 打破这种模式，否则它也应该是 FREETYPE_INCLUDE_DIRS。

链接器指令 (-lopengl32 -lglu32 -luser32) 在那里做什么？

if (WIN32)
    message(STATUS "LOADING OS --Windows--")
    include_directories(
    ${BOOST}/lib32-msvc-14.0 -libboost_timer-vc140-mt-gd-1_59 -libboost_log-vc140-mt-gd-1_59 -libboost_log_setup-vc140-mt-gd-1_59
    ${FREETYPE}/objs/vc2010/Win32/ -lfreetype263d
    )
endif ()

我很很困惑。这甚至意味着什么？您使用命令include_directories()，但看起来好像您正试图在此处提供链接器说明？添加链接依赖是通过target_link_libraries()...

即使您使用正确的命令，您也不会给出链接器指令 (-lfreetype263d)，而是列出链接目标，最好是由各种 find_package() 调用提供的链接目标，即 ${Boost_LIBRARIES}（不是 @987654333 @）和${FREETYPE_LIBRARIES}（不是${FREETYPE}）。

进一步：

set(CMAKE_CXX_FLAGS_COVERAGE "${CMAKE_CXX_FLAGS_RELEASE} -fprofile-arcs -ftest-coverage ")
add_definitions("-std=c++11")

如果您使用 Visual Studio，这些是编译器特定的选项，它们不会让您浮出水面。使用 if ( MSVC ) 和 if ( CMAKE_COMPILER_IS_GNUCC ) 检查您正在使用的编译器。
