将锈蚀项目链接到链接到其他cmake项目的cmake项目。
将锈蚀项目链接到链接到其他cmake项目的cmake项目。
提问于 2021-03-04 05:56:33
我正在使用cmake编译一个CMake项目，该项目依赖并编译其他CMake项目
这是我的build.rs
extern crate cmake;
use cmake::Config;
fn main() {
let dst = Config::new("src/cpp")
.define("COMPILE_TARGET", "DESKTOP_x86_64")
.define("FLAVOR", "DESKTOP")
.define("LIBOPENVPN3_NOT_BUILD_EXAMPLES", "TRUE")
.build();
println!("cargo:rustc-link-search=native={}", dst.display());
println!("cargo:rustc-link-lib=static=libopenvpn3");
println!("cargo:rustc-link-lib=dylib=stdc++");
}这就是我的src/cpp/CMakeLists.txt如何编译libopenvpn3
add_library(libopenvpn3 SHARED OpenVpnInstance.cpp)
target_link_libraries(libopenvpn3 crypto ssl lzo lz4 tins)但是，当我使用cargo build构建时，我从所有这些库crypto ssl lzo lz4 tins获得对对象的未定义引用。
我还试着制作libopenvpn3 STATIC，这样最终的libopenvpn3将包含所有所需的库：crypto, ssl, lzo, lz4, tins，比如：add_library(libopenvpn3 STATIC OpenVpnInstance.cpp)，但是我仍然会得到错误。我认为其他库(crypto, ssl, lzo, lz4, tins)只有在它们也是静态的情况下才会包含在libopenvpn3中。还是不想？
无论如何，我认为我应该重新链接到build.rs上的这些库，如下所示：
println!("cargo:rustc-link-lib=dylib=openvpn");
println!("cargo:rustc-link-lib=dylib=crypto");
println!("cargo:rustc-link-lib=dylib=lzo");
println!("cargo:rustc-link-lib=dylib=lz4");
println!("cargo:rustc-link-lib=dylib=tins");但是我不知道它们在哪里，因为它们是从CMakeLists.txt生成的，而且我不认为硬编码到生成它们的路径是个好主意。
我在这里该怎么办？

在CMakeLists.txt上，我在做：
install(TARGETS libopenvpn3 DESTINATION .)但后来我做了
install(TARGETS libopenvpn3 crypto ssl lzo lz4 tins DESTINATION .)所以它安装了所需的所有库。
然后，这个build.rs工作：
extern crate cmake;
use cmake::Config;
fn main() {
let dst = Config::new("src/cpp")
.define("COMPILE_TARGET", "DESKTOP_x86_64")
.define("FLAVOR", "DESKTOP")
.define("LIBOPENVPN3_NOT_BUILD_EXAMPLES", "TRUE")
.build();
println!("cargo:rustc-link-search=native={}", dst.display());
println!("cargo:rustc-link-lib=dylib=stdc++");
println!("cargo:rustc-link-lib=static=libopenvpn3");
println!("cargo:rustc-link-lib=static=crypto");
println!("cargo:rustc-link-lib=static=lzo");
println!("cargo:rustc-link-lib=static=lz4");
println!("cargo:rustc-link-lib=static=tins");
println!("cargo:rustc-link-lib=static=ssl");
}我不知道，但是，为什么我要把他们再次联系在铁锈。它们应该包含在libopenvpn3中，因为它们是静态的，不是吗？
