添加Sophus庫時CMake找不到Sophus的問題

很多人一開始使用Sophus庫時會碰到下面的錯誤：

CMake Error at CMakeLists.txt:5 (find_package):
  By not providing "FindSophus.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Sophus", but
  CMake did not find one.

  Could not find a package configuration file provided by "Sophus" with any
  of the following names:

    SophusConfig.cmake
    sophus-config.cmake

  Add the installation prefix of "Sophus" to CMAKE_PREFIX_PATH or set
  "Sophus_DIR" to a directory containing one of the above files.  If "Sophus"
  provides a separate development package or SDK, be sure it has been
  installed.


-- Configuring incomplete, errors occurred!
           

這時，CMakeLists.txt檔案中查找Sophus庫的語句多半是這麼寫的：

find_package(Sophus REQUIRED)
           

提供一種解決方案，觀看錯誤資訊，其實就是找不到Sophus庫和頭檔案的内容：

set(Sophus_INCLUDE_DIRS "放置你的Sophus頭檔案檔案夾路徑")
set(Sophus_LIBS "放置你的Sophus庫檔案的檔案夾路徑，指明相應的庫檔案")

比如，我的是這樣的：
set(Sophus_INCLUDE_DIRS "/usr/local/include/sophus")
set(Sophus_LIBS "/usr/local/lib/libSophus.so")

include_directories(
${Sophus_INCLUDE_DIRS}
 
)

然後再将你的執行檔案連結上Sophus庫檔案


           

這樣的話，上述編譯錯誤應該就可以消失了。
