install: CLI 装到 <prefix>/bin

[miaobyte]

问题

cli/（kvspace CLI）是独立 Cargo 项目，此前不参与 cmake --install —— 构建安装后系统里没有 kvspace 命令,它只出现在 release 包里。

变更

add_custom_target(kvspace-cli ALL
  COMMAND ${CMAKE_COMMAND} -E env "RUSTFLAGS=-L native=$<TARGET_FILE_DIR:kvspace>"
          cargo build --release --manifest-path .../cli/Cargo.toml
  DEPENDS kvspace)
install(PROGRAMS .../cli/target/release/kvspace DESTINATION ${CMAKE_INSTALL_BINDIR})

• 自动构建 CLI,并把本仓刚构建的 dispatch 前端目录交给链接器
• 安装到 <prefix>/bin —— prefix 默认 /usr,即 /usr/bin,与 kvlang 的 CLI 一致
• 无 cargo 时跳过并提示(不阻断库的安装)

验证

$ cmake -B build -DCMAKE_INSTALL_PREFIX=/tmp/kvsp-inst && cmake --build build -j
[100%] 构建 kvspace CLI（cli/）
$ sudo cmake --install build
-- Installing: /tmp/kvsp-inst/bin/kvspace          ← 新
-- Installing: /tmp/kvsp-inst/include/kvspace/*.h
-- Installing: /tmp/kvsp-inst/lib/kvspace/libkvspace.so.1.0.0
-- Installing: /tmp/kvsp-inst/lib/pkgconfig/kvspace.pc

$ /tmp/kvsp-inst/bin/kvspace
usage: kvspace <subcommand> [args]   (DSN from env KVSPACE)   ← 可运行
