Question

我有cmake 3.10.x，并下载了当前的protobuf源码3.6.1。我使用cmake创建了bin目录“ {PROTOBUF_SOURCE_DIR} / bin”，此库已成功建立。下一步，我想在基于cmake的项目中使用此自定义树。我有

set ( Protobuf_USE_STATIC_LIBS ON )

find_package( Protobuf REQUIRED )
if ( Protobuf_FOUND )
    message( STATUS "Protobuf version : ${Protobuf_VERSION}" )
    message( STATUS "Protobuf include path : ${Protobuf_INCLUDE_DIRS}" )
    message( STATUS "Protobuf libraries : ${Protobuf_LIBRARIES}" )
else()
    message( WARNING "Protobuf package not found -> specify search path via PROTOBUF_ROOT variable")
endif()

但是如何为cmake指定我的自定义目录树以查找必要的内容。

如果我使用find_package( Protobuf REQUIRED PATHS ${PROTOBUF_ROOT}/bin/lib/cmake/protobuf )，那么我将从cmake看到以下输出：

Protobuf version : 3.6.1
Protobuf include path : 
Protobuf libraries :

如何使cmake查找包含路径，库和协议编译器？

最后我有了一个解决方案-也许它将为其他人节省很多时间

set ( Protobuf_USE_STATIC_LIBS ON )

include(${PROTOBUF_ROOT}/bin/lib/cmake/protobuf/protobuf-config.cmake)
include(${PROTOBUF_ROOT}/bin/lib/cmake/protobuf/protobuf-module.cmake)
include(${PROTOBUF_ROOT}/bin/lib/cmake/protobuf/protobuf-options.cmake)
include(${PROTOBUF_ROOT}/bin/lib/cmake/protobuf/protobuf-targets.cmake)

find_package( Protobuf REQUIRED HINTS ${PROTOBUF_ROOT}/bin/lib/cmake/protobuf )
if ( Protobuf_FOUND )
    message( STATUS "Protobuf version : ${Protobuf_VERSION}" )
    message( STATUS "Protobuf include path : ${Protobuf_INCLUDE_DIRS}" )
    message( STATUS "Protobuf libraries : ${Protobuf_LIBRARIES}" )
    message( STATUS "Protobuf compiler libraries : ${Protobuf_PROTOC_LIBRARIES}")
    message( STATUS "Protobuf lite libraries : ${Protobuf_LITE_LIBRARIES}")
else()
    message( WARNING "Protobuf package not found -> specify search path via PROTOBUF_ROOT variable")
endif()

这对我很有用，指向我的自定义 Windows 静态构建：

model.wv.most_similar("glass")

由于某种原因，设置 set(Protobuf_USE_STATIC_LIBS ON) # add parent directory containing bin/protoc.exe, cmake/protobuf-config.cmake, lib/libprotobufd.lib (or .a), etc. list(APPEND CMAKE_PREFIX_PATH "/dir/where/protobuf/was/installed") find_package(Protobuf REQUIRED) 或 Protobuf_DIR 不起作用。

CMake：在自定义目录中找到protobuf软件包
