调试CMake find_library [英] Debug CMake find_library

问题描述

是否可以从CMake调试 find_library ?

Is it possible to debug find_library from CMake?

我想要的是考虑路径的列表.我的用例是像这样的呼叫

What I want is a list of considered paths. My use case is a call like

find_library (FOO_LIBRARY
              NAMES foo foo.so.0)

在我的系统上有/lib64/libfoo.so.0 .但是，CMake找不到它.我检查了 FIND_LIBRARY_USE_LIB64_PATHS 是否设置为 TRUE .

and there is /lib64/libfoo.so.0 on my system. However CMake does not find it. I checked that FIND_LIBRARY_USE_LIB64_PATHS is set to TRUE.

推荐答案

使用CMake 3.17，此

With CMake 3.17 this got added:

引入了"CMAKE_FIND_DEBUG_MODE"变量以打印更多内容查找cmake运行到标准错误期间的呼叫信息.输出是为人类消费而设计的，而不是为解析而设计的.

The "CMAKE_FIND_DEBUG_MODE" variable was introduced to print extra find call information during the cmake run to standard error. Output is designed for human consumption and not for parsing.

因此，您将 -DCMAKE_FIND_DEBUG_MODE = true 或-debug-find 传递给CMake命令.

So you pass either -DCMAKE_FIND_DEBUG_MODE=true or --debug-find to your CMake command.

以下是搜索libFOO时的示例输出:

Here is an example output when searching for libFOO:

find_library considered the following locations:

/usr/local/lib64/(lib)FOO(\.so|\.a)
/usr/local/lib/(lib)FOO(\.so|\.a)
/usr/local/lib64/(lib)FOO(\.so|\.a)
/usr/local/lib/(lib)FOO(\.so|\.a)
/usr/local/lib64/(lib)FOO(\.so|\.a)
/usr/local/(lib)FOO(\.so|\.a)
/usr/lib64/(lib)FOO(\.so|\.a)
/usr/lib/(lib)FOO(\.so|\.a)
/usr/lib64/(lib)FOO(\.so|\.a)
/usr/lib/(lib)FOO(\.so|\.a)
/usr/lib64/(lib)FOO(\.so|\.a)
/usr/(lib)FOO(\.so|\.a)
/lib64/(lib)FOO(\.so|\.a)
/lib/(lib)FOO(\.so|\.a)
/opt/(lib)FOO(\.so|\.a)
