Question

我在项目中创建了一些C ++库（VS术语中的解决方案），需要由其他两个项目使用。为此，我创建了一个FindDQSAnalyticsInfra.cmake文件，如下所示：

# DQSAnalyticsInfra
# -----
# Find the path to DQSAnalyticsInfra header files and libraries
#
# DEFINES
# ------
# DQSINFRA_ROOT - Root of the DQSAnalyticsInfra project
# DQSINFRA_INCLUDE_DIR - DQSAnalyticsInfra include directory
# DQSINFRA_LIBRARIES - Libraries required to link DQSAnalyticsInfra
# DQSINFRA_FOUND - Confirmation

set(DQSINFRA_LIBRARIES_LIST Utils Actor gtest)

find_path(DQSINFRA_INCLUDE_DIR Actor/Actor.h Utils/Log.h gtest/gtest/gtest.h
      ${DQSINFRA_ROOT}/include
      )

foreach(search_lib ${DQSINFRA_LIBRARIES_LIST}) 
    find_library(DQSINFRA_LIB NAMES ${search_lib}
                 PATHS
                 ${DQSINFRA_ROOT}/lib/Release #The problem is here
                )
    set(DQSINFRA_LIBRARIES ${DQSINFRA_LIBRARIES} ${DQSINFRA_LIB})
    if(DQSINFRA_LIB)
        unset(DQSINFRA_LIB CACHE)
        set(DQSINFRA_FOUND TRUE)
    else(DQSINFRA_LIB)
        set(DQSINFRA_FOUND FALSE)
        break()
    endif(DQSINFRA_LIB)
endforeach(search_lib)

if(DQSINFRA_INCLUDE_DIR AND DQSINFRA_LIBRARIES AND DQSINFRA_FOUND)
    set(DQSINFRA_FOUND TRUE)
    message(STATUS "Found DQSAnalyticsInfra. ")
    message(STATUS "Include Path: ${DQSINFRA_INCLUDE_DIR}")
    message(STATUS "Libraries ${DQSINFRA_LIBRARIES}")
else(DQSINFRA_INCLUDE_DIR AND DQSINFRA_LIBRARIES AND DQSINFRA_FOUND)
    set(DQSINFRA_FOUND FALSE)
    message(STATUS "DQSAnalyticsInfra not found.")
endif(DQSINFRA_INCLUDE_DIR AND DQSINFRA_LIBRARIES AND DQSINFRA_FOUND)

mark_as_advanced(DQSINFRA_INCLUDE_DIR DQSINFRA_LIBRARIES)

此文件正常。问题是在这个文件中使用的find_library命令中，我将路径硬编码为$ {DQSINFRA_ROOT} / lib / Release。这意味着我无法使用此文件链接到Debug版本（我必须手动更改文件以使用$ {DQSINFRA_ROOT} / lib / Debug）。关于如何解决这个问题的任何想法。谢谢。

使用可为target_link_libraries指定的debug和optimized个关键字：

find_library(DQSINFRA_LIB_DEBUG NAMES ${search_lib} 
                 PATHS
                 ${DQSINFRA_ROOT}/lib/Debug
                )

find_library(DQSINFRA_LIB_RELEASE NAMES ${search_lib}
                 PATHS
                 ${DQSINFRA_ROOT}/lib/Release
                )

set(DQSINFRA_LIBRARIES optimized ${DQSINFRA_LIB_RELEASE} debug ${DQSINFRA_LIB_DEBUG})

让自定义Find * .cmake文件根据visual studio构建类型找到不同的库（Debug / Release）
