我目前正在尝试从GitHubLink安装gr-matchstiq，遇到了问题。代码不再符合CMake的标准。
具体来说，cmake 2.6引入了逻辑目标名称必须唯一的策略（请参阅：CMP0002）。然而，目标“ALL”被重复使用。我相信是这样的，因为我得到的错误：

$ cmake -Wno-dev ../
-- Build type not specified: defaulting to release.

cmake/Modules/GrPython.cmake：115中的代码是：

add_custom_target(${_target} ALL DEPENDS ${ARGN})

cmake/Modules/GrPython.cmake：214中的代码是：

GR_UNIQUE_TARGET("pygen" ${python_install_gen_targets})

我几乎没有使用cmake的经验，所以我也不确定哪种修复方式最安全
1.在根CMakelists.txt文件中，添加行（注意：这不起作用，但也许我做错了什么）：
set_property(GLOBAL ALLOW_DUPLICATE_TARGETS TRUE)
1.将'ALL' cmake/Modules/GrPython.cmake：115更改为类似于'ALL_PY'的内容-即
add_custom_target(${_target} ALL_PY DEPENDS ${ARGN})
1.以某种方式修改GR_UNIQUE_TARGET函数（GrPython.cmake的第107-116行）：

########################################################################
# Create an always-built target with a unique name
# Usage: GR_UNIQUE_TARGET(<description> <dependencies list>)
########################################################################
function(GR_UNIQUE_TARGET desc)
    file(RELATIVE_PATH reldir ${CMAKE_BINARY_DIR} ${CMAKE_CURRENT_BINARY_DIR})
    execute_process(COMMAND ${PYTHON_EXECUTABLE} -c "import re, hashlib
unique = hashlib.md5('${reldir}${ARGN}').hexdigest()[:5]
print(re.sub('\\W', '_', '${desc} ${reldir} ' + unique))"
    OUTPUT_VARIABLE _target OUTPUT_STRIP_TRAILING_WHITESPACE)
    add_custom_target(${_target} ALL DEPENDS ${ARGN})
endfunction(GR_UNIQUE_TARGET)

或者，我还应该做些什么？
PS -我需要做的另一个修复是在第95-102行：

########################################################################
# Sets the python installation directory GR_PYTHON_DIR
########################################################################
execute_process(COMMAND ${PYTHON_EXECUTABLE} -c "
from distutils import sysconfig
print (sysconfig.get_python_lib(plat_specific=True, prefix=''))
" OUTPUT_VARIABLE GR_PYTHON_DIR OUTPUT_STRIP_TRAILING_WHITESPACE
)

最初，Python的print语句没有Python所要求的“（“&“）”3）
PPS -我不知道如何处理或找到类型错误，所以稍后会处理它们。
