我已经从源代码成功构建了 openssl、zlib 和 nghttp2。我曾经git repo安装每个库，并且没有弄乱它们中的任何一个的安装路径。他们位于这里
coke@DESKTOP-1B2KV2R:~$ ls
curl nghttp2 openssl wolfssl zlib
coke@DESKTOP-1B2KV2R:~$
现在，我想使用这些库中的每一个构建 libcurl 7.78.0 DEV。从位于 INSTALL.MD 中的安装指南，我会做
./configure --with-wolfssl=PATH --with-zlib=PATH
然后运行
make
然后出于非错误目的，我会像这样在 make install 中包含 sudo
sudo make install
当我尝试用 wolfssl 构建它时，我得到了这个：
Host setup: x86_64-pc-linux-gnu
Install prefix: /usr/local
Compiler: gcc
CFLAGS: -Werror-implicit-function-declaration -O2 -Wno-system-headers -pthread
CPPFLAGS: -isystem PATH/include -isystem PATH/include -isystem /usr/local/include
LDFLAGS: -LPATH/lib -LPATH/lib -L/usr/local/lib
LIBS: -lnghttp2 -lwolfssl -lm -lz
curl version: 7.80.0-DEV
SSL: enabled (WolfSSL)
SSH: no (--with-{libssh,libssh2})
zlib: enabled
这表明 wolfssl 已启用，zlib 也已启用......所以我运行 make 命令并得到这个

如果我指定了 wolfssl，为什么它会尝试查找 openssl 库文件？
所以相反，我想也许出于某种原因我需要 wolfssl 的 openssl？所以我尝试了这个：
./configure --with-openssl=PATH
得到这个
configure: error: PATH is a bad --with-openssl prefix!
无论我输入什么，路径都是“错误的前缀”。我究竟将 --with-wolfssl/openssl 标志指向哪里？每个相应的下载目录中有许多文件。我在 Ubuntu 18.04 中使用 wsl。我还尝试按照此处的建议添加 without-ssl 标志https://www.wolfssl.com/wolfssl-build-option-in-curl/ ./configure 的完整输出并制作：

安装 libssl-dev 后（由于评论说 wolfssl 使用了一些 openssl 文件，我安装了）我已经摆脱了丢失的 openssl 头文件错误，但是我现在在运行时得到了这个make

运行这个``` cmake -D CMAKE_USE_WOLFSSL=YES -D CMAKE_USE_NGHTTP2=YES CMAKE_USE_ZLIB=YES "/home/cok e/curl" -- curl version=[7.80.0-DEV]
Produces this:

-- Found NGHTTP2: /usr/local/lib/libnghttp2.so
-- Could NOT find LibSSH2 (missing: LIBSSH2_LIBRARY LIBSSH2_INCLUDE_DIR)

-- Configuring done

-- Build files have been written to: /home/coke/curl-build
然后 cmake --build 。生成上面给出的 libcurl.so
