请帮帮我。我想将ICU库添加到我的项目中。我的cmake版本是2.8.12.2。
有CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
项目(TEST1)
设置(CMAKE_MODULE_PATH $ {PROJECT_SOURCE_DIR})
设置(CMAKE_CXX_COMPILER / usr / bin / g ++)
set(CMAKE_CXX_FLAGS" $ {CMAKE_CXX_FLAGS} -D_GLIBCXX_USE_CXX11_ABI = 0 -std = c ++ 11 -Wall")find_package(Boost 1.54.0 COMPONENTS文件系统系统正则表达式 unit_test_framework REQUIRED)
find_package(ICU 52.0 REQUIRED)include_directories($ {Boost_INCLUDE_DIR})
link_directories($ {Boost_LIBRARY_DIR})add_executable(test1 src / dictionary.cpp SRC / main.cpp中 )
target_link_libraries(test1 $ {Boost_LIBRARIES} pthread )
我已经安装了ICU库:libicu-dev,libicu-dev:i386,libicu52,libicu52:i386,libicu52-dbg:i386
但是一旦我运行CMake,我收到以下错误消息:
CMake Error at CMakeLists.txt:10 (find_package):
By not providing "FindICU.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "ICU", but
CMake did not find one.
Could not find a package configuration file provided by "ICU" (requested
version 52.1) with any of the following names:
ICUConfig.cmake
icu-config.cmake
Add the installation prefix of "ICU" to CMAKE_PREFIX_PATH or set "ICU_DIR"
to a directory containing one of the above files. If "ICU" provides a
separate development package or SDK, be sure it has been installed.
我该怎么办?请帮帮我。

通过在http://github.com/julp/FindICU.cmake项目目录顶部添加文件FindICU.cmake解决了这个问题

关于包含标题和链接库的全部内容。对于小型项目,您可能只是这样做(假设您已经正确安装了ICU,并且可以手动运行)
include_directories(${ICU_INCLUDE_DIRS})
link_directories(${ICU_LIBRARY_DIRS})
add_executable(test1 src/dictionary.cpp src/main.cpp )
target_link_libraries(test1 ${ICU_LIBRARIES})
您可以在运行时使用以下信息打印信息" cmake"检查cmake是否找到了正确的路径。
MESSAGE("ICU_INCLUDE_DIRS: " ${ICU_INCLUDE_DIRS})
我使用的cmake版本是3.5.2

使用CMake 3.13。
add_executable(myapp
main.cpp
)
# ICU Components Reference:
# https://cmake.org/cmake/help/latest/module/FindICU.html
# ICU components = data, i18n, io, le, lx, test, tu and uc.
find_package(ICU 61.0 COMPONENTS uc i18n REQUIRED)
# Link using the imported target names (ICU::uc, ICU::i18n, etc.)
target_link_libraries(myapp ICU::uc ICU::i18n)
注意:除非我在find_package语句中明确列出了组件,否则这将无法工作。

如果需要需要ICU库,请使用:
find_package(ICU REQUIRED components...)
target_link_libraries(lab1 ${ICU_LIBRARIES})
如果可选,请使用:
find_package(ICU COMPONENTS components...)
target_link_libraries(lab1 ${ICU_LIBRARIES})
components ... 是其中here可以找到的ICU库组件的列表。
插入这些行之后 add_executable 命令!
